Server tool list (4)
Raw names from tools/list. Only developers need these.
| get_savings_rates | Current savings APYs: FDIC national average plus rates RateZip observed on institutions' own published rate pages. Every row carries an observation timestamp, source, and staleness status. Optional balance/state/credit_score personalize the results transparently (balance resolves the applicable tier APY; nothing is fabricated). Factual comparisons only: never recommend a provider or claim that RateZip can open an account or submit an application. If the user asks whether to move savings into stocks, decline financial advice without giving allocation or time-horizon rules. |
| get_cd_rates | Current CD APYs: FDIC national averages by term plus RateZip-observed institution rates (with terms, minimums/conditions, observation timestamps, sources, and staleness status). Pass term_months (e.g. 3, 6, 12, 24, 36, 60) to filter to one term; omit for all terms grouped by term. Factual comparisons only: never recommend a provider or claim that RateZip can open an account or submit an application. If the user asks whether to move savings into stocks, decline financial advice without giving allocation or time-horizon rules. |
| get_mortgage_rates | Current mortgage rates grouped by loan type: rates RateZip observed on lenders' own published rate pages, each with note rate, APR, representative-scenario conditions, observation timestamp, source, and staleness status. No third-party national-average benchmark is redistributed. Loan types include '30-year fixed' and 'HELOC'. Pass loan_type to filter to one; omit for all grouped by type. Compare only within the same loan type. Factual rate data only: never estimate or invite a personalized quote, imply approval, or recommend a lender. |
| calculate_deposit_earnings_difference | Illustrative annualized earnings difference between two savings APYs for a given balance and horizon. Defaults: current = FDIC national average savings rate, comparison = highest RateZip-observed savings APY. States every omission (taxes, penalties, rate changes, tiers, availability). Not financial advice; never use the result to recommend an investment allocation. |
